There is no picture to reference from so I’m going to take a wild guess and say A
Answer:
<h2>100 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 25 × 4
We have the final answer as
<h3>100 J</h3>
Hope this helps you
Answer:
<h3>The answer is 25 m/s²</h3>
Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula

where
v is the velocity
t is the time
From the question
v = 100 m/s
t = 4 s
We have

We have the final answer as
<h3>25 m/s²</h3>
Hope this helps you
1). Frequency = (1/period) = 1/(20sec) = (1/20) per sec .
2). Frequency= (3 waves) / (4 sec) = (3/4) (per sec)
Period = (1/freq) = 1/(3/4 per sec) = (4/3) sec
3). Speed= (freq) x (wavelength) (2 per sec) x (5 m) = (2 x 5) ( m per sec)
Speed doesn't depend on amplitude.
Answer:
61.25N to the positive x axis
